Tip: To allow external users (those outside your firewall) and sites (Cisco Unified MeetingPlace systems outside your network) to access a meeting and the associated meeting materials, make sure that Allow External Web Participants is set to Yes for the meeting. This parameter is set by the meeting scheduler from the New Meeting scheduling page, and it is only visible if your Cisco Unified MeetingPlace system has an external site-that is, a Web Server located in an Internet-accessible segment of your network, such as in a DMZ zone.
